[PATCH v4] pci: prevent putting nvidia GPUs into lower device states on certain intel bridges
...but there are couple of things that
stand out where we may go into a different path. One of them is this in
the PGOF() method:
If (((OSYS <= 0x07D9) || ((OSYS == 0x07DF) && (_REV == 0x05))))
The ((OSYS == 0x07DF) && (_REV == 0x05)) checks specifically for Linux
(see [1] and 18d78b64fddc ("ACPI / init: Make it possible to override
_REV")) so it might be that Dell people tested this at some point in
Linux as well. Added Mario in case he has any ideas.
Previously I suggested you to try the ACPI method tracing to see what
happens inside PGOF(). Did you have time to try it?...
